Description
Vynález se týká elektrolytu pro katodické vylučováni slitiny nikl-kobalt-fosfor z vodných roztoku.The invention relates to an electrolyte for cathodic deposition of a nickel-cobalt-phosphorus alloy from aqueous solutions.
Slitiny nikl-kobalt-fosfor mají velmi dobrou odolnost proti opotřebeni, zejména při vyšších teplotách. Vyloučené povlaky dosahuji po tepelném zpracováni tvrdosti povlaku chromových.Nickel-cobalt-phosphorus alloys have very good wear resistance, especially at higher temperatures. The deposited coatings reach the hardness of the chromium coatings after heat treatment.
Elektrolyty pro vylučováni slitin nikl-kobalt-fosfor^uváděné v literatuře/jsou nestabilní a neumožňuji vylučováni slitin s různým obsahem jednotlivých složek. Další nevýhodou dosud známých elektrolytů je vysoké vnitřní pnutí” vyloučených povlaků, které je příčinou jejich praskáni při vylučováni povlaků o větších tloušťkách.The electrolytes for the precipitation of nickel-cobalt-phosphorus alloys reported in the literature are unstable and do not allow the precipitation of alloys with different contents of the individual components. Another disadvantage of the prior art electrolytes is the high internal stress of the deposited coatings, which causes them to crack when depositing coatings of greater thickness.
Uvedené nevýhody odstraňuje elektrolyt podle vynálezu, jehož podstata spočívá v tom, že obsahuje nikl a kobalt ve formě rozpustných sulfosalicylanů, každý v koncentraci 10 až 500 g/ 1000 ml vody, nebo ve formě komplexů, vzniklých z rozpustné soli niklu a kobaltu, každé v koncentraci 10 až 500 g/1000 ml vody a z rozpustné soli kyseliny sulfosalicylové v koncentraci 10 až 500 g/1000 ml vody nebo z rozpustné soli kyseliny 1,2 dihydroxibenzen 5,5 disulfonové v koncentraci 10 až 500 g/1000 ml vody, fosfor ve formě rozpustných jednomocných nebo trojmocných sloučenin v koncentraci 1 až 100 g/1000 mlvody, rozpustný halogenid v koncentraci 1 až 100 g/1000 ml vody a připadne an i on„ aktivní smácedlo v koncentraci 0,01 až 10 g/1000 ml vody.The above-mentioned disadvantages are eliminated by the electrolyte according to the invention, which comprises nickel and cobalt in the form of soluble sulfosalicylans, each at a concentration of 10 to 500 g / 1000 ml of water, or in the form of complexes formed from soluble nickel and cobalt salts. 10 to 500 g / 1000 ml water and from soluble sulfosalicylic acid salt at 10 to 500 g / 1000 ml water or from 1,2 dihydroxibenzene 5,5 disulfonic acid soluble salt at 10 to 500 g / 1000 ml water, phosphorus in in the form of soluble monovalent or trivalent compounds in a concentration of 1 to 100 g / 1000 ml of water, a soluble halide in a concentration of 1 to 100 g / 1000 ml of water and, optionally, an active wetting agent in a concentration of 0.01 to 10 g / 1000 ml of water.
Elektrolyt podle vynAÍOH umožňuje vylučovat slitinové povlaky, které obsahují 10 až 75% hmot. kobaltu, 0,1 až 15% hmot. fosforu a zbývající % hmot. niklu. Vyloučené povlaky jsou polo2The electrolyte according to the invention makes it possible to deposit alloy coatings containing 10 to 75 wt. % cobalt, 0.1 to 15 wt. % phosphorus and the remaining wt. nickel. The deposited coatings are semi2
242 555 lesklé, hladké a pružné. Vnitrní pnuti těchto povlaku je velmi nízké, a proto je možno vylučovat i povlaky o větších tloušťkách bez nebezpečí jejich praskání.242 555 glossy, smooth and flexible. The internal stresses of these coatings are very low, and therefore coatings of greater thickness can be deposited without the risk of cracking.
Pro doplňování elektrolytu kovem během pokovování je možno s výhodou použít slitinových anod nikl-kobalt nebo dvojitého anodového okruhu.Preferably, nickel-cobalt alloy anodes or a double anode circuit can be used to replenish the electrolyte with metal during plating.
V případech, kdy elektrolyt obsahuje nikl a kobalt ve formě komlexú, které v něm vznikají z rozpustných solí niklu a kobaltu a z rozpustné soli kyseliny sulfosalicylové nebo 1,2 dihydroxibenzen 5,5 disulfonové, je možno použít jako výchozích solí niklu a kobaltu^napr. síranu, chloridu, fluoridu nebo sulfamátú.In cases where the electrolyte contains nickel and cobalt in the form of complexes formed therein from soluble salts of nickel and cobalt and from soluble salts of sulfosalicylic acid or 1,2 dihydroxibenzene 5,5 disulfonic acid, nickel and cobalt starting salts can be used, e.g. sulphate, chloride, fluoride or sulphamates.
'Fosfor, který je do elektrolytu přidáván zejména ve formě, rozpustného fosfornanu, napr. sodného, draselného nebo nikelnatého a ve formě kyseliny fosforité, příznivě ovlivňuje mikrotvrdost vyloučených povlaku.Phosphorus, which is added to the electrolyte in particular in the form of soluble hypophosphite, e.g. sodium, potassium or nickel and in the form of phosphorous acid, favorably affects the microhardness of the deposited coatings.
Přídavek rozpustného halogenidu, např. ve formě solí sodných, draselných nebo nikelnatých, zlepšuje rozpustnost anod.The addition of a soluble halide, e.g. in the form of sodium, potassium or nickel salts, improves the solubility of the anodes.
Pro odstranění vodíkového pittingu je vhodný přídavek anionaktivního smáčedla. Zvláště výhodné je použití sulfonovaných esteru kyseliny jantarové.The addition of anionic surfactant is suitable to remove hydrogen pitting. The use of sulfonated succinic esters is particularly preferred.
Elektrolyt pracuje při provozních teplotách 20 až 80’C, v oblasti pE 2,5 až 5,5· Katodová proudová hustota se pohybuje •v 2 v rozmezí 1 až 10 A/dm .The electrolyte operates at operating temperatures of 20 to 80 ° C, in the pE range of 2.5 to 5.5.
Povlaky, vyloučené z elektrolytu podle vynálezu, jsou vhodné jako ochranné povlaky pro zvýšení životnosti obráběcích nástrojů, pro renovační účely a ke zhotoveni skořepin pro lisovaní plastických hmot.The coatings deposited from the electrolyte according to the invention are suitable as protective coatings for increasing tool life, for renovation purposes and for producing shells for molding plastics.
Vynález je objasněn na čtyřech příkladech provedení, jimiž však není jeho rozsah omezen ani vyčerpán.The invention is illustrated by four exemplary embodiments, but the scope thereof is not limited or exhaustive.
